Lithium-ion battery is a widely used rechargeable battery. It has high operating voltage, small size, light weight, high energy density, long cycle life, can be fully charged quickly in a short time, and allows discharge temperature Wide advantages. In addition, lithium-ion batteries have the advantages of low self-discharge current, no memory effect, and no environmental pollution. Its global supply is continuously increasing.

Lithium-ion batteries, as a new generation of rechargeable power sources, have the advantages of long cycle life, large volume density, high operating voltage, high safety performance, and wide operating temperature range. They are the mainstream development direction of current rechargeable batteries. It also has the characteristics of low maintenance requirements and no memory effect. It can be charged and discharged at any time during the battle, and requires almost no battlefield maintenance, reducing logistical burden. Therefore, it has been valued and developed by the military of all countries. In recent years, lithium-ion batteries have been widely used in military equipment such as individual combat systems, submarines, unmanned aerial vehicles, and aerospace vehicles, and have shown broad application prospects in land, sea, air, and space.

Lithium battery maintenance methods, how to maintain lithium batteries in winter? Lithium batteries are easy to enter the market due to their advantages of compactness, lightness and environmental protection. The heavy, short life and heavy pollution lead-acid batteries can no longer meet our needs. The lithium battery has been cured, and it can be used for 5-7 years. Good maintenance habits can greatly help extend the life of your lithium battery. What are the precautions for lithium battery maintenance? How to maintain the lithium battery in winter? Lithium battery manufacturers will answer your questions below.

The working principle of lithium battery discharge, what is the cut-off voltage? The termination voltage of lithium battery discharge means that after the lithium battery is discharged to a certain voltage, it should not be continued to discharge, otherwise it will cause irreversible loss of some of the lithium battery ’s power and serious damage to the battery. The nominal voltage of a single lithium battery is generally 3.7V, and the termination voltage is 2.75V.

Batteries packed in aluminum cases are sealed with laser sealing technology and fully sealed. The aluminum case technology is very mature, and the material technology, such as the inflation rate, expansion rate and other indicators, is not high.

The LiFePO4 battery has the advantages of high working voltage, large energy density, long cycle life, good safety performance, small self-discharge rate, and no memory effect.

18650 is the originator of lithium-ion batteries a standard lithium-ion battery model set by Japan's Sony Corporation in order to save costs, where 18 represents a diameter of 18mm, 65 represents a length of 65mm, and 0 represents a cylindrical battery.

Precautions for charging lithium batteries:

1. When charging the lithium battery, it is best to choose the original special charger, otherwise it will affect or damage the polymer lithium battery.

2. When charging lithium batteries, it is best to use slow charging. Avoid fast charging as much as possible. Repeated charging and discharging will also affect the life of lithium batteries.

The internal resistance of a battery refers to the resistance to the current flowing through the battery during operation. It includes ohmic internal resistance and polarization internal resistance. Polarization internal resistance includes electrochemical polarization internal resistance and concentration polarization internal resistance.

How to pack lithium batteries?

1. Make sure that lithium batteries are individually packaged in completely closed inner packaging, such as blister packaging or cardboard to ensure that each battery can be protected;

2. Cover and protect the lithium battery, so as to avoid short circuit or contact with any conductive material in the package, which may cause short circuit;
